Synthesis and Evaluation Analysis of the Indicator Information in Nuclear Safeguards Applications by Computing With Words
This paper aims at the handling and treatment of nuclear safeguard relevant information by using a linguistic assessment approach. This is based on a hierarchical analysis of a State's nuclear activities in a multi-layer structure of the evaluation model. After a hierarchical analysis of the State's nuclear activities on the basis of the IAEA Physical Model, the addressed objective is divided into several less complex levels. The overall evaluation can be obtained step by step from those lower levels. Special emphasis is put on the synthesis and evaluation analysis of the Physical Model indicator information. Accordingly, the aggregation process with the consideration of the different kinds of qualitative criteria is in focus. Especially, the symbolic approach is considered by the direct computation on linguistic values instead of the approximation approach using the associated membership function. In this framework, several kinds of ordinal linguistic aggregation operators are presented and analyzed. The application of these linguistic aggregation operators to the combination of the Physical Model indicator information is provided. An example is given to support and clarify the mathematical formalism
MESURE DE LA SECTION EFFICACE 12C(γ, xn) DU SEUIL JUSQU'A 33 MeV.
La réaction 12C(γ, xn) a été produite dans une cible de carbone naturel par le rayonnement de freinage du linac. Les photoneutrons sont détectés par un système du type Halpern. La méthode d'analyse de Penfold et Leiss et celle de Cook ont été appliquées. La forme de la résonance géante est conforme à celle observée dans les dernières expériences.The 12C(γ, xn)-reaction was produced in a natural carbon target by the bremsstrahlung beam from the linac. The photoneutrons are detected by a Halpern-type system. Penfold and Leiss' analysis method as well as Cook's method were applied. The shape of the giant resonance is in good agreement with that observed in previous experiments
MEMS-IC integration for RF and millimeterwave applications
This paper reports on the MEMS-IC
integration for microwave and millimeterwave
applications. The integration is based on the System In
Package (SiP) approach achieving high performances and
integration density level at microwave and millimeterwave
frequencies thanks to the mixing of state-of–the-art
technologies both for active (SiGe or RF-MOS
technologies) and passive (dielectric based technology)
devices/circuits. This concept can also take full benefit of
the MEMS technologies to provide various smart
functionalities to microsystem. The proposed approach is
illustrated through different applications which outline
the design issues of such heterogeneous microsystem
